Yes, but why is the value that it is and not higher or lower? From my (basic) research it seems, it could be plus or minus 20% a different value, and the current Universe would still be feasible.
- marcellus23 2y agoWell, it has to be _some_ value, right? I mean, if we were in a universe where it was 20% greater, you would be asking the same questions.
- belter 2y agoNo, the point is that if it was 20% bigger we would not be here to ask those questions :-) Stars fusion or weak atomic interactions would not work. Maybe Hari Seldon decided....
